Materials engineering is concerned with investigating the properties of existing materials and substances in order to create new materials and items with enhanced chemical and physical properties.These new or improved materials are frequently created for specific applications that can then be transferred to different industries.Materials engineers also improve production processes, reduce the cost and environmental impact of materials and decrease instances of materials-related parts failure. Material engineering is involved in everything from high-strength, lightweight parts for the aerospace and automotive industries to biomedical devices, food wrapping, heat-proof ceramics for furnaces, and materials for your smartphone or tablet screen
